Which of the following natural elements is the primary element in computer chips?
Answer: B) Silicon
Silicon is the primary element in computer chips because it's a semiconductor. Its electrical conductivity can be controlled to create transistors and integrated circuits, which are the fundamental components of computer chips. This property makes silicon ideal for electronic devices, forming the basis of modern computing technology. : Software (1) Its full form is 'GNU's Not Unix' (2) It was started by Richard Stallman (3) It's an open-source software (4) It is not compatible with Unix CGPSC (Pre) 2021 Solution: Correct Answer is It is not compatible with Unix Explanation: The GNU system was explicitly designed to be a free Unix-like operating system. A core design goal was compatibility with Unix, allowing it to run existing Unix software and for developers to easily port their applications. Therefore, the statement claiming it is "not compatible with Unix" is incorrect. -

The main purpose of software is to convert data into
Answer: B) Information
The primary purpose of software is to convert data into information. Data refers to raw facts and figures, while information is processed, organized, and meaningful data that aids in decision-making. For example, a program takes student marks (data) and produces a report card (information). Software, which is a set of instructions, controls the hardware to perform this conversion. This fundamental process is the core of any computer system's functionality, enabling users to derive meaningful insights from raw inputs. -
Q6Computer · MemoryIBPS (exam not specified) 2014
Main memory works in coordination with ........... .
Answer: C) CPU
Main Memory, or primary memory, works in direct coordination with the CPU (Central Processing Unit). The CPU is the brain of the computer that executes all instructions. Main Memory, which includes RAM (Random Access Memory), acts as a active workspace to provide the CPU with fast access to data and instructions. When a program runs, its instructions and data are first loaded into the main memory, and the CPU reads from and writes to this memory directly. This direct access is crucial for the computer's speed and efficiency. Other options, like a special function card or Intel (a company name), are not part of this core coordination mechanism of the main memory. -

Which of the following storage devices directly interacts with the CPU?
Answer: C) Primary Storage
Primary Storage, also known as main memory or RAM (Random Access Memory), directly interacts with the CPU. This is the memory where currently executing programs and data are stored. The CPU needs it for fast data access. Due to its direct connection via the data bus, the CPU can instantly read and write instructions from primary storage, enhancing processing speed. Secondary storage (like a Hard Disk) and Tertiary Storage are slower compared to primary storage and do not communicate directly with the CPU; instead, they interact through Input/Output channels. -

Which of the following tasks is not performed by a computer's CPU?
Answer: C) Permanently storing data
The CPU (Central Processing Unit) is the primary processing component of a computer that performs fetching instructions, interpreting instructions (decoding), and data processing (execution). It controls all arithmetic and logical operations in the computer. However, permanently storing data is not a function of the CPU this task is performed by storage devices such as hard disks, SSDs, or other memory devices.

Determine the output of the following formula if the cell values are as follows: B2 = 120, B3 = 130, B4 = 140, B5 = 150, B6 = 160? E3 = IF(AND(B2>=B4, B2<=B5), B6, B7)
Answer: C) 0
The formula IF(AND(B2>=B4, B2<=B5), B6, B7) evaluates the AND condition B2>=B4 (120>=140) and B2<=B5 (120<=150). The first condition is false since 120 is less than 140. As the AND condition fails, the formula returns the value of B7. The B7 cell value is considered 0 as it's empty or undefined. -
